Abstract (en)
[origin: WO2016007938A1] A system comprises a wellbore having a plurality of casings disposed therein and one or more electromagnetic coils disposed within the wellbore. The one or more electromagnetic coils are configured to generate and direct one or more excitation signals toward the plurality of casings and receive one or more response signals based on interactions of the one or more excitation signals with the plurality of casings. The system further comprises a casing evaluation module comprising a processor and memory and communicably coupled to the one or more electromagnetic coils. The casing evaluation module is operable to determine whether a defect exists in at least one of the plurality of casings using a first response signal received from the one or more electromagnetic coils and elemental defect information, the elemental defect information comprising a plurality of combinations of small defect information.
